Trying to pick a guinea pig breed for your first pet? The American is the one most people start with, and for good reason.
American guinea pigs have short, smooth coats that come in colors like black, brown, white, and red. They typically measure 10 to 12 inches long and weigh between 2 and 3 pounds.
They’re friendly with kids and easy to groom. That simple coat means less brushing and fewer tangles compared to long-haired breeds like the Silkie.
Knowing their traits, breeding history, and personality will help you decide if they’re the right fit.
What is the American guinea pig?
The American Guinea Pig is a small rodent that’s often kept as a pet. They’re social creatures that enjoy being around people, other guinea pigs, and other animals.
What are the American guinea pig breeds?
There are two main American guinea pig breeds: the English and the Wallaby.
The English guinea pig variety is the most common. It has short fur that’s available in a variety of colors, including black, brown, white, and red.
The Wallaby is less common, and it has longer fur that’s typically white or cream-colored.
Where does the American guinea pig come from?
The Andes Mountains in South America. That’s where guinea pigs originally come from, domesticated by the Inca Empire in present-day Peru.
The Incas valued them highly, even using them in religious ceremonies.
Over time, guinea pigs spread to other parts of the continent and eventually made their way to Europe.
How did guinea pigs come to the United States?
English settlers brought the first guinea pigs to Jamestown, Virginia in 1627. The timing is kind of wild when you think about it.
They caught on fast as colonial pets, and researchers started using them for medical studies too.
Because of their popularity, people soon started to breed guinea pigs in North America. This domestic breeding led to the development of the American guinea pig, which is distinguished from its European cousins by its larger size and longer hair.
American guinea pig traits
Short, smooth fur makes grooming a breeze. Color options include black, brown, white, and plenty more.
Length and Weight
They’re usually between 10 and 12 inches long, while their weight varies between 2 and 3 pounds.
Appearance
Big, expressive eyes and slightly pointed noses give them a lot of personality. Their ears are rounded and small, sitting close to the head.
Compact bodies with short legs complete the look.
Behavior
Similar to all other guinea pig breeds, they’re very active and enjoy exploring their habitat. They’re also very social animals and enjoy interacting with their human companions.
American guinea pig personality
Herd animals at heart, Americans love having company - whether it’s other guinea pigs or their human family. Curiosity drives them to explore constantly and play with whatever toys you provide.
Male guinea pigs can sometimes fight if they weren’t raised together. This is why it’s best to get two males that are around the same age if you want them to be friends.
Outgoing doesn’t even begin to cover it. Owners describe them as “cuddly” and “affectionate,” and most genuinely enjoy being held and petted.
Playfulness is another strong suit. Toy chasing and ball rolling keep them (and you) entertained.
Make sure to be around while your guinea pig plays with toys, as they can sometimes get caught up in them and hurt themselves.
American guinea pig breeding facts
Breeding Americans isn’t hard, but it does require some planning. A few things to know before you start.
Choosing the guinea pigs
They’re social creatures, and it’s best to keep them in pairs or small groups. When breeding, choose a healthy pair of animals that are of similar size and temperament.
If you’re planning to breed your guinea pigs for show, select animals that conform to the standard for their particular variety.
Setting up a breeding colony
When setting up a breeding colony, provide each pair or group with its own cage. This helps reduce stress and minimize the spread of disease.
Introduce the pair slowly, giving them time to get used to each other before breeding.
Preparing a nesting box
You’ll need to prepare a nesting box for the female guinea pig. This can be made from cardboard or wood and should be large enough for the female to move around comfortably.
Provide plenty of hay, as this will help keep the nesting box clean and dry.
When are guinea pigs ready for breeding?
Both male and female guinea pigs reach sexual maturity at around four months of age, but you shouldn’t breed them until they’re at least six months old.
When the female is ready to breed, she’ll usually give birth to two or three baby guinea pigs, called “pups.” The pups need to be kept warm and dry, so check on them regularly.
The gestation period lasts 59 days, and mothers usually give birth without any trouble. Allow the mothers to recover for a few days before introducing them back into the colony.
The pups should be weaned at around three weeks of age.
American guinea pig health and lifespan
American guinea pigs have an average lifespan of 4-6 years, although this can vary depending on diet, exercise, and genetics.
A guinea pig who’s well-fed and lives in a clean environment tends to live longer than those who don’t. A guinea pig that gets plenty of exercise is less likely to develop health problems related to obesity.
Some guinea pigs are born with neurological or genetic conditions that shorten their life expectancy. While there’s no guarantee that a guinea pig will live to a ripe old age, taking good care of them gives them the best chance possible.
Caring for American guinea pigs
American guinea pigs are relatively easy to care for. They don’t require a lot of space and can be kept in a small cage or enclosure.
Provide your guinea pig with plenty of hay, fresh vegetables, and water. Give them access to a hiding place, as guinea pigs are prey animals and tend to feel stressed without somewhere to retreat.
They should be groomed regularly, and their nails should be trimmed every few weeks. Make sure their cage is cleaned regularly.
These guinea pigs are social animals and enjoy interacting with their human companions. Most can be trained to do simple tricks and will often come when called by name.
Compared to breeds like the Teddy guinea pig or Rex, the American’s short coat requires minimal grooming effort.
American guinea pig breed health notes
Your American relies on you for everything. Daily interaction matters more than people realize.
Sit with your guinea pig each day and offer a few gentle strokes. Ten minutes goes a long way.
That routine helps them feel secure and gives you both a chance to build trust.
They’re known for being vocal creatures and will often “purr” when they’re content. If you notice your pet making high-pitched noises or chattering their teeth, this could be a sign of distress.
Watch the portions - Americans tend to overeat. Fresh vegetables and hay should form the foundation, with supplements only if your vet recommends them.
How to train your American guinea pig (step-by-step guide)
Training your American guinea pig is a great way to bond with your pet and give them some mental stimulation.
Here’s a step-by-step guide to getting started:
- Choose a command. Pick a word or phrase like “come,” “sit,” or “spin.” Make it easy to say and distinct from other commands.
- Get your guinea pig’s attention. Call their name or make a loud noise before you start training.
- Reward good behavior. When your guinea pig does what you’ve asked, reward them with a treat or verbal praise. This reinforces the behavior.
- Be patient. Training takes time, so don’t get discouraged if your guinea pig isn’t catching on right away. With practice, they’ll be performing tricks in no time.
Homemade treats for your American guinea pig
Commercial food covers the basics, but homemade treats add variety and nutrition. Plus, they’re fun to make.
Hay balls
Collect a handful of fresh hay, then add a small amount of water. Use your hands to form the hay into small balls and place them in your guinea pig’s cage.
Hay balls add variety to their diet and provide essential nutrients.
Carrot pellets
Cook some carrots until they’re soft, then mash them into a paste. Use a spoon to drop small pellets of carrot paste onto a baking sheet.
Bake in a preheated oven for about 15 minutes, then let them cool before giving them to your guinea pig.
Herb-sprinkled hay
Sprinkle some dried herbs onto a piece of fresh hay. Rosemary, parsley, and thyme all make good choices for guinea pigs.
Place the herb-sprinkled hay in your guinea pig’s cage and watch them enjoy their fragrant treat.
Your guinea pig will go nuts for any of these, and you’ll know exactly what went into them.
Final Thoughts
The American guinea pig is the best starter breed for new owners. Their short coat, friendly personality, and hardy health make them low-maintenance compared to long-haired breeds or more delicate varieties like the Baldwin.
Give them fresh hay, clean water, vegetables, and a buddy to hang out with. That’s really all they need to thrive.
If you’re on the fence about which breed to get, the American is a safe bet. They’re forgiving of beginner mistakes and will reward you with years of popcorning, purring, and personality.
